Praia de Acaú, Sandy beach in Pitimbu, Brazil.

Praia de Acaú is a sandy beach along the coast of Paraíba state that stretches for several kilometers with a wide, golden shoreline. Natural tidal pools form when the tide goes out, creating shallow areas along the sand.

The settlement of Pitimbu takes its name from the Tupi indigenous language, meaning 'water spring of smoke' or a place where water and steam meet. This name reflects the region's deep connection to water and natural features.

Fishermen work the waters daily using methods passed down through generations, and their catch reaches beachfront restaurants that serve regional seafood dishes. This rhythm of fishing and eating fresh catch is woven into how people live here.

Acaú lies in the Acaú district, in the south of Pitimbu, near the Goiana River basin on the Pernambuco–Paraíba border. Access is by road from Pitimbu or Goiana. The beach is busiest during the summer holidays, when it serves as a meeting point for residents of Goiana.

Acaú is nicknamed "Praia do Oi" by the people of Goiana, in neighbouring Pernambuco, because this stretch of sand in southern Pitimbu is where they gather at holiday time. The beach lies in the Acaú district, within the Goiana river basin on the Pernambuco–Paraíba border.
